glfw3 specific refrences missing with glfw3

Question

when I had tried to compile the example code for glfw3 on http://www.glfw.org/documentation.html (copy/pasted to test compilation), I got the following errors:

/tmp/ccCdEKoi.o: In function main':
example.cpp:(.text+0x38): undefined reference toglfwCreateWindow'
example.cpp:(.text+0x5b): undefined reference to glfwMakeContextCurrent'
example.cpp:(.text+0x7a): undefined reference toglfwWindowShouldClose'
collect2: error: ld returned 1 exit status

I am compiling with g++ example.cpp -o example -lGL -lglfw and when I installed the latest glfw 3.0.2, it installed without problems.

Answer 1

GLFW3 builds as libglfw3 by default, not libglfw as GLFW2 did. So you're probably still linking against your GLFW2 installation.

Solution:

g++ example.cpp -o example -lGL -lglfw3
